WAGON-AX LE.

SPECIFICATION forming part of Letters Patent No. 372,581, dated November l, 1887.

Application tiled June 28, 1887. Serial blo-12,735. (No model.)

.To all whom, il? may concern:

Be it known that l, JOHN L. THOMPSON, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Vagon-Axles; and I do hereby ticolare that the following is a full, clear, and exact description of the same.

The object ofniy invention is the production Io of a serviceable axle that is light, strong, and inexpensive. This object I accomplish by the construction illustrated in the accompanying drawings, in which- Figure l shows a rear elevation of the axle I5 With its spindles, the bolster, and ends of the hounds and reach. Fig. 2 is an enlarged plan view of a portion ofthe inverted axle and its spindle. Fig. Sisa longitudinalseetional view of the same ou thelineXX, Fig. 2; and Fig. 4

2c is a transverse section on the line Y Y of Fig. 2.

Ain the drawings designates a ehanneliron bar serving as the axle, B, a wooden cap-bar secured to the top of the axle, and Othe usual bolster.

c c are the hounds, and e the reach.

The spindles Dare formed on separate pieces, the square stocks d of which tit closely in the ends of the channel of the axle, and bands or axle-clips b, around the stocks d and axle and 3o cap-piece, imite these parts. These-parts are further secured together and to the bolster by bolts ct, extending from the flattened portion d of the spindle-stock t0 the top of the bolster through the hounds. Additional bolts, e, are passed through the web ofthe channel-iron and the flat part d ot' the spindle-stock. The heads n ofthe bolts a and c may be madetotwithin the channel of the axle, so that they cannot turn, and the nuts for the bolts may be at the upper ends, those for the bolt'sa in mortises in 4o the top ofthe bolster, and those for the bolts e on top of the axle and tting in niortises in the under side ofthe cap-piece B. ll'pret'erred, however, the nuts n may be on the lower ends of the bolts and adapted to be turned in the channel ot' the axle, as shown inthe drawings.

An axle constructed as described possesses the requisites ofstreugth, lightness, and cheapness.

Having described my invention, what I 5o claim, and desire to secure by Letters Patent, is-

A Wagonaxle consisting of a channel-iron bar having a rectangular channel and placed with its web uppermost, and spindles having square portions fitting in the ends ofsaid channel and ilat portions extending within the channel, and bolts through said dat portions of the spindle-stocks and the web of the channel-iron, and adapted to secure the same to- 6o gether and to the bolster, substantially as set forth.

JOI-IN L. THOMPSON.
